Phytochemical screening and Antifungal activities of Parthenium hysterophrous L (Asteraceae) was carried out in laboratory. Distilled water and methanol extracts of the leaves of plant was prepared. Five phytopathogenic fungi: Alternaria brassicae, Botrytis cinerea, Fusarium oxysporum, Phytophthora capsici and Sclerotium rolfsii were tested at different concentrations (50 mg/ml, 100 mg/ml, 150 ...

Fourteen saxicolous lichens from trans-Himalayan Ladakh region were identified by morpho-anatomical and chemical characteristics. The n-hexane, methanol and water extracts of the lichens were evaluated for their antioxidant capacities. The lichen extracts showing high antioxidant capacities and rich phenolic content were further investigated to determine their cytotoxic activity on human HepG2 ...

The ethnobotanical significance and antimicrobial potential of various extracts of Blumea lacera was investigated. The plant was found to be used in many folk preparations. Antimicrobial potential of the plant was evaluated against three bacterial and one fungal species. Two different solvents water and methanol were used for extraction purposes. Among the different extracts investigated, water...

conclusions ethanol extracts of p. granatum (pericarp, leaves, flowers, seeds) have antibacterial effects against p. haemolytica which has shown resistance to all studied antibiotics. background continuous researches on drugs that solve the problem of growing number of resistant bacteria are important. objectives this research aims to investigate the effectiveness of anti-bacterial properties s...

BACKGROUND Pleurostylia capensis is a large tree that can reach the maximum height of 20 m long, and it have been traditionally used as cosmetic, for steam bath, ritual body wash, and as a purgative to treat symptoms of witchcraft. Using ethanol, chloroform, dichloromethane (DCM), ethyl acetate (EA), and water extracts, leaves, bark and roots of Pleurostylia capensis were investigated scientifi...

The aim of this study was to evaluate whether water soluble compounds present in aqueous extracts from seven Mediterranean demosponges exert biological activity towards matrix metalloproteinases (MMPs), which represent important pathogenic factors of human diseases. Aqueous extracts were tested on LPS-activated cultured rat astrocytes, and levels and expression of MMP-2 and MMP-9 were assessed ...

BACKGROUND Alzheimer's disease (AD) is one of the common neurodegenerative disorders among elderly. The purpose of this study was to determine the neuroprotective effect and mechanisms of action underlying the Terminalia chebula extracts and ellagic acid by using beta-amyloid25-35 (Aβ25-35)-induced cell toxicity in an undifferentiated pheochromocytoma (PC12) cell line. MATERIALS AND METHODS T...

Various extracts of flowers of Cassia fistula Linn (Leguminosae) such as petroleum ether (60-80°), chloroform, acetone, ethanol, aqueous, and crude aqueous extracts and two fractions of ethanol extract were tested for antihyperglycemic activity in glucose-overloaded hyperglycemic rats. The effective antihyperglycemic extracts and fraction were tested for their hypoglycemic activity at two dose ...

In this contribution, pressurized liquid extraction (PLE) has been employed to isolate bioactive compounds from three native Romanian plants, oregano (Origanum vulgare), tarragon (Artemisia dracunculus) and wild thyme (Thymus serpyllum). Different PLE conditions have been tested including extraction with water, ethanol and their mixtures in a wide range of extraction temperatures (50-200°C), an...

The antioxidant activities of water extract (WE), ethanol extract (EE), residue water extract (RWE) and petroleum ether (PF), ethyl acetate (EF), n-BuOH (BF) and water (WF) fractions of the ethanol extract from Eupatorium Lindley DC were investigated for the first time. Total phenolics content, DPPH radical scavenging activities, superoxide radical scavenging activities, total reduction capabil...
